The application obstacles of BIM technology in green building project and its key role path analysis

The purpose of this study is to identify and analyze the application barriers and internal mechanisms of BIM technology in green building projects. It is found that BIM technology can effectively integrate information and optimize management, but its application still faces economic externalities and requires government intervention to promote its development. Through the analysis of five aspects of technology, economy, management, policy and environment, we identified 16 influencing factors and focused on nine key factors, such as insufficient technology maturity and high-cost issues. Research shows that policy and management factors play a fundamental role in BIM adoption and influence economic effectiveness through complex interactions. Based on the ISM-ANP coupling model, we propose that the government should encourage technological innovation and personnel training to promote the effective application of BIM technology in green buildings. This study provides a theoretical reference for the application of BIM and green building on a global scale.
